Present: M.D., A.D., S.Š, J.S.
General:
- S.Š:
- MD:
- Wrote the HDgeant Section in the proposal and added his latest plots.
- AD:
- Revised rates, now accounting for 50% tagger efficiency for lower photon energy, and for the smaller Lorentz boost at Ebeam=5.5 GeV
- Added a section table of beam time request/timeline summary.
- The table Includes a spindance done with GlueX detector. It assumes 8h based on the following:
- 0.5% raw asymmetry (half of the 1% physics asymmetry due to PbPt~0.6 and assuming a slight 20% dilution from background)
- 20kHz of good rate. (We expect 40khz of good rate, but I assumed harsh online cuts so that we stay away from regions where we may have high dilution (forward angles)/poor efficiency).
- 5 points at different Wien angles. (we usually do 3 but maybe we should be generous for a first time in Hall D.)
- Each point then takes about 1.4h, for a total of 7h. Then adding a 1h overhead makes 8h.
- The table Includes a spindance done with GlueX detector. It assumes 8h based on the following:
